Newton’s Universal Law of Gravitation - Physics - Gravity Course, Class 2

What You Will Learn?

• Let's explore Newton’s Universal Law of gravitation together!.
• Sir Isaac Newton was a real genius, he realized that the force that makes an apple fall is of the same nature than the one that makes planets turn! This was a thought from the 17nth century!.
• This class will present his insight and the formula that came out of it. Then, it will be your turn to be active by solving 4 exercises. In all cases, you can enjoy a detailed correction of these exercises, spiced with fascinating physical facts that rise from the Universal Law of Gravitation..
• *** Content of the class ***.
• Video 1: The lesson itself presenting the Universal Law of Gravitation..
• Video 2: Two exercises with their corrections..
• Video 3: Two more exercises with their corrections..
• Exercises are provided also as pdf files under two forms: Full picture (to view on a screen), or printable ( so that you can work on the exercises away from the computer). Answers are provided also in a pdf document..
•  .
• *** This class is part of a larger course named “Gravity, The Basics”.***.
• “Gravity, The Basics” explores the elementary notions of Newtonian gravity..
• Class 1: “Linear Motion” (because being comfortable with this notion will allow you to make the most of the full course). This class can be taken by itself..
• Class 2: “Newton’s Universal Law of Gravitation”, which you can consider as a doorway to the deeper dive we will carry out in the next classes..
• Class 3: “Gravitational Fields”.
• Class 4: “Circular Motion”.
• Class 5: “Orbital Motion”.
• Class 6: “Wrapping-up and Gravity Quiz”.
